Hi, I am using PayPal REST API 1.9.1 in my dotnet core project. I have created sandbox account and when I am trying to make any payment getting "Payee account is invalid." error. Api endpoint is "/v1/payments/payment" and payment method is "credit_card". Below is code snippet: string accessToken = new PayPal.Api.OAuthTokenCredential(config).GetAccessToken(); var apiContext = new PayPal.Api.APIContext(accessToken); // A transaction defines the contract of a payment. var transaction = new PayPal.Api.Transaction() { amount = new PayPal.Api.Amount() { currency = "USD", total = totalAmount, details = new PayPal.Api.Details() { shipping = shipping, subtotal = subTotal, tax = tax } }, description = description, item_list = new PayPal.Api.ItemList() { items = new List<PayPal.Api.Item>() { new PayPal.Api.Item() { name = itemName, currency = "USD", price = "1", quantity = "5", sku = "sku" } }, shipping_address = new PayPal.Api.ShippingAddress { city = "Johnstown", country_code = "US", line1 = "52 N Main ST", postal_code = "43210", state = "OH", recipient_name = "Basher Buyer" } }, invoice_number = invoice_number }; // A resource representing a Payer that funds a payment. var payer = new PayPal.Api.Payer() { payment_method = "credit_card", funding_instruments = new List<PayPal.Api.FundingInstrument>() { new PayPal.Api.FundingInstrument() { credit_card = new PayPal.Api.CreditCard() { billing_address = new PayPal.Api.Address() { city = "Johnstown", country_code = "US", line1 = "52 N Main ST", postal_code = "43210", state = "OH" }, cvv2 = card.CVV, expire_month = Convert.ToInt32(card.ExpirationMonth), expire_year = Convert.ToInt32(card.ExpirationYear), first_name = firstName, last_name =lastName, number = card.CardNumber, type = card.CardType } } }, payer_info = new PayPal.Api.PayerInfo { email = "payermail" }, }; // A Payment resource; create one using the above types and intent as `sale`, 'order', 'none' or `authorize` var payment = new PayPal.Api.Payment() { intent = "sale", payer = payer, transactions = new List<PayPal.Api.Transaction>() { transaction } }; // Create a payment using a valid APIContext var createdPayment = payment.Create(apiContext); Same code is working fine with payment method "paypal" by making minor changes in request. Please let me know how to make it working for card payments. It is urgent. Thanks
